A Clinical Evaluation of an Intraparenchymal Intracranial Pressure Transducer

Abstract

The Camino pressure transducer is accurate experimentally over a range of clinically relevant intracranial pressures (ICPs). Three clinical studies have shown that intraparenchymal pressure mirrors intraventricular pressure. In two a different type of transducer was used, and one was a mixed animal and human study [3, 4, 2]. This study compares intraparenchymal pressure, mea- sured with a Camino fibre-optic transducer, with intraventricular pressure, using a fluid filled catheter, in unconscious head injured patients and evaluates the clinical efficacy of the Camino system.
